White Sands footprints reveal ice age environmental shifts
Expanded excavations at White Sands National Park in New Mexico have allowed researchers to refine the chronology of the oldest known human footprints in North America. These findings offer a clearer picture of the landscape during the last ice age. Scientists are using these geological clues to understand how early human inhabitants interacted with and responded to abrupt environmental and climate transformations in the region.
